1. First choose Start, Settings, and then Control Panel to open the Control Panel.
2. Choose Modems.
3. Select the entry for your modem, and choose the Properties button to open the Modem Properties dialog box.
4. Choose the Connection tab, and then the Advanced tab button to open the Advanced Connection Settings dialog box.
5. The Extra Settings text box in the dialog box may already have some text in it. This text is actually a set of commands for the modem. Modem commands vary from one modem to the next, but most use the command MO - that's a zero, not a capital 0 - to tell the modem to keep the speaker off at all times. First make sure that the text box does not already have a command beginning with M. (And note that &MO, /MO, and MO are three different commands.) If there is an M command already, replace it with an MO command. If there is not an existing M command, simply type MO in the text box. (It's okay to add it at the end of other commands that are already there.) Choose OK, and Windows will send the command to the modem every time it dials a connection. If this does not work, you'll need to check your modem manual to see if the modem has an oddball command for controlling the speaker.
